Located by Trincomalee, Sri Lanka, in the heart of the Indian Ocean, its strategic importance has shaped its history.

In 1942 the Imperial Japanese Navy attacked Trincomalee harbour and sank three British warships anchored there.

Trincomalee Harbour, formerly a British naval base, was taken over by the Inaams Ceylonese government in 1956 to be developed as a commercial port.

At present SLPA is in the process to re-develop Trincomalee as a metropolis growth center.
